Now we use FOIL to rewrite the expression.
FOIL is:
First
Outer
Inner
Last
That's the order we will be distributing the variables in the parentheses.

Combine like terms:

That's your final answer.
Hope that helps.
It lies in the third quadrant. Best of luck!
Not so sure about the second one, but the first one is pretty simple:
The area of a circle = pi x radius^2
Since you need to find the area of the entire dvd, I'm assuming they mean if the hole in the center wasn't there, so add that to the diameter.
12+1.5 = 13.5
Half of the diameter is the radius, so half of 13.5 = 6.75
Now, multiply pi (3.14) by the radius, but have the radius squared. You'd write the equation like this:
3.14 x 6.75^2 (or on paper, the ^2 would be a small two diagonal from the 5)
Actual answer: 143.06625
You can round that to 143.
Answer:
128
Step-by-step explanation:
Billy has 55 stamps and his brother Tommy has 73. Add 73 and 55 together. 55+73=128
Answer:
X is your answer bc when coordinates are flipped over the x-axis the y coordinate goes negative
